ORGAN-ACTION.

SPECIFICATION forming part of Letters Patent No. 326,624, dated September 2.2, 1885.

Application tiled March G, 1884.

' following to be a description of our said invention sufficiently full, clear,and exact to enable others skilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings, which form a part of this specification.

y Our present invention relates to certain im -provements in construction, arrangement, and

operation of various parts of the action, as hereinafter fully explained,with aview to the production of a convenient, efficient, and more desirable instrument, and to afford an action mechanism that can be manufactured with practical economy and dispatch.

The particular features of invention claimed are hereinafter definitely specified.

In the drawings, Figure l represents an end view of our improved organ-action. Eig. 2 is a transverse vertical section showing` the relative arrangement of the stops, connections, and operating parts of the action. Fig. 3 is a plan and section detail showing the arrangement of the crank-levers in connection with the fulcrum-bar. Eig. JC is a transverse vertical section of the action, showing the grandexpression connections in open position, and also illustrating the construction of the depressing devices used in eases where it is desired to operate a single crank-lever by two separate movements or by two separate pulls. Eig. 5 is a longitudinal section through the vsound-board, showing the back of the action and cranlelever mechanism drawn to smaller scale; Figo, a back view of the reed-board and mutes longitudinally, showing the arrangement of the auxiliary reeds,which operate only with the grand-expression devices. Fig. 7 is a vertical section through the detachable connecting device by which the cranklevers are joined to the mute-actuating wires, drawn to larger scale. Fig. 8 is a back view of the same. Fig. 9 is a front view of the crank-lever head and section of the mutecon- (No model.)

nection wire. Fig. l() is an end view of the crank-lever end.

In the construction of our present organ-action the soundingboard S, tubeblock T, playing-valves V, pitmanpins o, manual-keys V, and keysupporting frame w are all constructed and arranged substantially in the ordinary manner, and therefore need not bcherein more particularly described.

A designates the name board or brace, in which the stop pull-bars P are supported in the manner indicated.

B denotes a fulcrumbar on which the wire crank-levers C have support. Said bar B eX- tends across the instrument beneath the rear portion A of the brace, and back of the manual-keys. Its ends are connected with supporting-pieces B, that rest upon the top of the key-frame, and which in turn form a support for the brace A in the Inanner illustrated, the several cheeks or ends being llush with each other on the outer side.

The key-frame, the fulcrum-bar devices, and the brace mechanism are each made up as separate parts, and the three are detachably connected together by means of the double hooks or swinging lock-bars D, at the ends oi' the action. Said lock-bars are pivoted at b on the fulcrum-bar cheeks B, and their ends hook onto studs LZ and d', respectively xed in the ends of the keyframe and brace-piece, as illustrated in Fig. l. By swinging back the bars D the brace A, with the pulls P, can be removed from the action; then by pressing back the hooks b, at the front part of the ends B', the fulcrum-bar B and parts connected therewith can be readily removed. rPhis feature of making the brace and pull mechanism separate and detachable from the fulcrum-bar and its connections, and the latter separable and readily detachable from the other portions ofthe action, is of our invention, and is of con` siderable practical utility and convenience in the manufacture of the actions, and the facility of putting them into their cases, as well as for 9 convenience for repairs. The crank-levers C are made of wire bent 'in the form indicated, with arms that extend upward and forward, having ends c, turned at an angle beneath the pulls P, to be acted upon by the depressing roo access to the reed-blocks and reeds, and as readily replaced, since it is only necessary to raise the bearings or pivots from the recess to free the swell, there being no permanent connections along its edges. The swells K and K are provided with rolls Z on the outer end of their cranked pivot-bearings, which are en-` gaged by the lifting-bar L, which latter is actuated by means of the ordinary knee-pad (not shown) for opening the swells as required. The swell K is also connected for operation to one ofthe levers C of the stop-pull mechanism, as indicated at K3, Figs. 4 and 5, so that it can be raised by drawing the stop, or in connection with the grand-expression roller G when the latter is operated. Combined with the action we employ a partial set of reeds, N, the tones of which are ranged between the violoncello 7 and sub-base sets, and which are arranged to be brought into aetion by the grand-expression mechanism only. The arrangement of the devices for bringing into action this partial set of reeds in the present instance is shown in Figs. 4, 5, and 6. The mute M is connected by wire m2 to an angle-lever, N', which is in turn ljoined by the wire m3 to an arm, a, fixed on the expressionroller G, so that when said roller G is pressed back (see Fig. 4) the mute M will be raised and the reeds N permitted to speak as the manual-keys are depressed, but at all other times except when the grand expression is operated the reeds N are closed in and remain silent, the partial set of reeds being brought into action with the grand expression only. A feature of our invention is the arrangement of the devices for effecting this result.

O indicates the sub-base action, which may be of ordinary construction. Its mute M2 is connected by the Wires m4 to a change-lever,which in turn is connected to one of the crank-levers C to be operated by a stop-pull, as indicated.

Rand B designate the connections for working the swell and bellows-indicator mechanism, which is located at the central part of the name-board A. This indicator mechanism is not a part of our present invention.

Y indicates the pitman-pin for opening the valve Y of the tremolo mechanism, which is arranged in the manner illustrated in Fig. l. The rod Y is depressed by an inclined lug, F3, on one of the stop-pulls P when said stop is drawn for bringing the tremolo into operation.

What we claim as of our invention, and desire to secure by Letters Patent, is-

l. The construction and arrangement of organ action mechanism, as described, viz.: with the brace-section A, the fulcrumbarsection B B', and the key-frame section w as separate detachable parts, with connecting devices, as hooks D, which permitof their ready removal one part from the other, substantially as and for the purpose set forth,

2. The combination, with the sounding devices and key-frame in an organ-action, of the detachable fulcrum-bar B, carrying the cranklevers and grand-expression roller, the detachable brace A, carrying the pull-bars, and the connecting-hooks D, pivoted to the fulerum-bar ends, as at I), and adapted to engage studs cl el', respectively fixed on the ends of said brace and key-frame, for detachably retaining said parts in position, substantially as set forth. I

3. The crank-lever C, provided with the wood end block c3, fitted with conical recess c and end slit, e2, in combination with the mute-actuating wire m, screw-threaded at the end and provided with the wooden button E, screwed directly upon said wire and having the shank c extending through the recess cL of said lever end block, as set forth.

4. The combination of the fulcrum-bar B, the cranked levers C, expression-roller G, and the adjusting screw-buttons I, substantially as shown and described,for the purposes specilied.

5. The combination of the pull P, provided with the depressing-piece F, the wire cranklever C, supported in the grooved fulcrumbar B and having the offset top end,c,and dependent arm c, with joint-block c3, the muteactuating wire m, and the expression-roller G, having adjustable studs I, substantially as and for the purpose set forth.

6. The combination, with the pull-bar I? and wire crank-lever C, of the inclined actuating-lug F2, connected to said pull in the manner shown, with the attaching-screw f and adjusting-screw f, for the purpose set forth.

7. The combination, with the reed-board S, tube-block T, and swell-board II, in a reedorgan action, of the centrally-pivoted swells K K', having their bearing-pivot k and closing-spring J,secured in arecess formed on the edge of the cheek-piece or end frame by the button It in the manner described, whereby ready detachment of the swell can be effected, substantially as and for the purpose set forth.

S. In a reed-organ action, the combination, with the expression mechanism and tubeboard, of the auxiliary reeds N, their mute M, and the link devices mlm, angle-lever N, and arm u,connecting said imite with the expression -roller G for: operation therewith substantially as and for the purpose set forth.
